Recently wind energy has been alternatively used as a renewable energy resource instead of the mostly used fossil fuels due to their increasing scarcity and environmental issues. This work is to propose a structural design and analysis procedure for development of a 500 W class small wind turbine system which will be applicable to domestic use at a relatively low speed region like Korea. Structural analysis including load case study and stress, deformation, buckling, vibration and fatigue estimation was performed. In addition, the blade should be safe from the impact damage due to FOD (foreign object damage) including bird strikes. MSC Dytran was used to analyze the bird strike phenomenon on the blade, and the applied method, Arbitrary Lagrangian-Eulerian, was evaluated by comparison with the previous study results. Finally, the structural test was carried out and its test results were compared with the estimated results for evaluation of the designed structure.

Objective: This case study reports the effects of treating a gastric cancer patient who had undergone gastrectomy with Korean medicine.Methods: After gastrectomy, a 77-year-old female patient received acupuncture, electroacupuncture, herbal medicine (<i>Banhabaekchulchunma-tang</i>, <i>Banhahubak-tang</i>), and moxibustion for one month.Results: After treatment, changes were observed in the patient’s numeric rating scale (from 7 to 2); visual analog scale (from 8.7 to 2.6); Short Form-36 Health Survey scores (physical from 20 to 48 and mental from 14 to 53); Functional Dyspepsia-Related Quality of Life results (from 84 to 41); and Korean Nepean Dyspepsia Index (from 63 to 32).Conclusion: Korean medical treatment for dyspepsia following gastrectomy is worthy of further research.

This study examined how consumer choices (i.e., selecting food safety certified products, health-related products, and familiar brands) affect the purchase of Korean native chicken (KNC) and the demographics that influence KNC purchases using secondary consumer panel data from the Rural Development Administration of Korea. The grocery purchase data from 654 Korean households between 2017 and 2019 were used; the propensity for food safety certified products was measured by the purchasing frequency of Good Agricultural Practice (GAP) and Hazard Analysis and Critical Control Point (HACCP) products, and the propensity for health-related products was measured by the purchasing frequency of home meal replacement (HMR) and hedonic products. The propensity to purchase familiar brands was measured using a questionnaire. Logistic regression was used to examine the determinants of the KNC purchase experience, and multiple linear regression was used to determine the factors that influenced the KNC purchase frequency. The results showed that unemployed women purchased more safety certified products, health-related products, familiar brands, and KNC. These findings suggest that targeting consumers with differential marketing strategies may help promote KNC consumption. This study identified factors that influence KNC purchases, which is important for understanding consumer behavior and revitalizing the market.
